We started with used HP’s. Then found a great buy on a Konica Minolta on Amazon. This was good until we had a power surge and the power supply was blown. Now we use a Kyocera all in one. Our cost per page for B&W toner is less than $0.01. We have it under a lease and we have a maintenance contract to make sure we are always running. We are averaging around 20,000 pages a month.
